Cori "Coco" Gauff is the most exciting new tennis star. The 15-year-old recently beat Venus Williams, a five-time Wimbledon winner, in a qualifier. The victory was considered quite a shock, and many believe Gauff has what it takes to be a champion.

Arthur Ashe made history in 1975 when he won Wimbledon a few days before his 32nd birthday, beating Jimmy Connors, the defending champion. He was the only black man ever to win the singles title at Wimbledon, the US Open, and the Australian Open.

"You cannot be serious" shouted McEnroe, after an umpire denied him a serve. The player went off on a tangent, "you guys are the absolute pits of the world, you know that?" he yelled. Almost 40 years later, the lines are etched into everyone’s memory. Eventually, the American won the game.

Steffi Graf gets a Golden Slam - That was just the beginning. Graf became the first tennis player ever to get a Golden Slam. She won all four Grand Slam singles titles, as well as the Olympic gold medal, all in the same year.

No one expected 30-year-old Goran Ivanisevic to win Wimbledon. He'd lost three finals previously, and had never managed to get a Grand Slam title. What's more, he was only at the 2001 tournament thanks to a wild card spot.

The underdog wins - The Croatian underdog played Pat Rafter (right) in the final. Goran won the game, finally claiming a Wimbledon title. In the process, he became the only men's singles player (to this day) to win Wimbledon on a wild card spot.

2001’s final was the start of a new era for tennis. Pete Sampras (right) was a seven-time Wimbledon champion and a true force to be reckoned with on the court. Quite a challenge for rising star Roger Federer (left).

It was 19-year-old Roger’s debut at Wimbledon, and the competition was Sampras' court. But Federer pulled through, showing unmatched determination. Roger would go on to become an all-time great, while Sampras would never win Wimbledon again.

Venus Williams (top) was going for her third Wimbledon singles title in 2005. She hadn’t won a Grand Slam title in four years, so it was all to play for in the final against Lindsay Davenport (bottom).

Williams vs. Davenport - It was a match unlike any other. The two matched each other’s strengths perfectly and it became the longest ladies' final ever. In the end, Williams won, with a 9-7 score in the last set.

What they got was the longest match in tennis history. The intense face-off lasted three days, with a combined time of 11 hours and five minutes. 183 games later, Isner came out on top, with a well-earned victory unlike any other.
